What is the fractional decrease in the value of free-fall acceleration g for a particle when it is lifted from the surface to an elevation `h`? `(h lt lt R)`
Which of the following graphs shows the variation of acceleration due to gravity g with depth h from the surface of the earth ?
Find the percentage decrease in the acceleration due to gravity when a body is take from the surface of earth to a height of 32 km from its surface. ["Take" R_(e )=6.4xx10^(6)m]
Find the percentage decrease in the acceleration due to gravity when a body is taken from the surface of earth of a height of 64 km from its surface [ Take R_(e) = 6.4 xx10^(6) m ]
At what depth from the surface of the earth, the acceleration due to gravity will be half the value of g on the surface of the earth ?
At what depth from the surface of the earth, the acceleration due to gravity will be (1)/(4) th the value of g on the surface of the eath ?
What minimal value can the Brewester angle have when light falls from air on to the surface of any dielectric?
At what depth from the surface of the earth, the acceleration due to gravity will be (1)/(4) th the value of g on the surface of the earth ?
Assertion : If rotation of earth about its own axis is suddenly stops then acceleration due to gravity will increase at all places on the earth. Reason : At height h from the surface of earth acceleration due to gravity is g_(h)=g(1- (2h)/R_(e)) .
If the acceleration due to gravity at the surface of the earth is g, the work done in slowly lifting a body ofmass m from the earth's surface to a height R equal to the radius of the earth is
An earth satellite of mass m revolves in a circular orbit at a height h from the surface of the earth. R is the radius of the earth and g is acceleration due to gravity at the surface of the earth. The velocity of the satellite in the orbit is given by
